Sound-source localization when listeners and/or sound sources move

The Journal of the Acoustical Society of America, 2021
In the dynamic everyday world, sound sources and/or listeners move when animals attempt to localize sound sources. Determining sound-source locations in these dynamic scenarios requires several computations by the brain. The auditory-spatial cues (Interaural Time Differences, ITDs; Interaural Level Differences, ITDS; and spectral cues associated with ...

SPRSound: Open-Source SJTU Paediatric Respiratory Sound Database

IEEE Transactions on Biomedical Circuits and Systems, 2022
It has proved that the auscultation of respiratory sound has advantage in early respiratory diagnosis. Various methods have been raised to perform automatic respiratory sound analysis to reduce subjective diagnosis and physicians' workload.

Sources of Underwater Sound and Their Characterization

2016
Because of the history of sonar and sonar engineering, the concept of "source level" is widely used to characterize anthropogenic sound sources, but is it useful for sources other than sonar transmitters? The concept and applicability of source level are reviewed for sonar, air guns, explosions, ships, and pile drivers. International efforts toward the

SOUND SOURCE DIRECTIVITY CONSIDERING SOURCE MOVEMENT

Inter-Noise 2022, 2023
When the source moves, frequency modulation (Doppler effect) occurs in the radiated sound, and the directivity of source changes. In addition, the source can be not located in a direction from the direction of arrival of radiated sound. Therefore, the sound pressure directivity may differ depending on whether the source is static or moving.

The Conical Sound Source

The Journal of the Acoustical Society of America, 1945
An asymptotic expansion has been derived from a formula given by W. N. Brown, which allows the plotting of directional and response curves for a vibrating cone in an infinite baffle. The results are compared with those pertaining to a flat disk of same radius.

Sound Source Separation Apparatus And Sound Source Separation Method

The Journal of the Acoustical Society of America, 2011
To shorten an output delay while a high sound source separation performance is ensured when a sound separation process based on an ICA method is performed. A second Fourier transform process execution cycle t2 for obtaining a second frequency-domain signal S1 used as an input signal of a filter process is set shorter than a first Fourier transform ...

Method and apparatus for diagnosing sound source and sound vibration source

The Journal of the Acoustical Society of America, 2002
Acoustics or vibrations at a plurality of predetermined positions are respectively detected in the form of analog values, and the detected analog values are respectively converted into digital values. The digital values are subjected to digital filtering by using the digital values and filter factors, and at least one of the filter factors is changed ...

Influence of sound source width on human sound localization

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Free-field sound localization experiments generally assume that a loudspeaker can be approximated by a point-source; however, a large loudspeaker may extend beyond the width that two sources can be discriminated. Humans can accurately discriminate sound source locations within a few degrees, thus one might expect localization precision to decrease as a
